With the intensification of global climate change, governments around the world have introduced policies to encourage
the development of renewable energy. China has explicitly stated in the 14th Five Year Plan to vigorously develop solar energy,and industrial
and commercial photovoltaic projects have received strong support under this policy background.
If a company can effectively utilize solar energy, it can not only reduce the burden of electricity bills and promote sustainable development,
but also enhance the company's image, which is in line with future development trends.
At the same time,energy storage technology is receiving increasing attention as a solution that can store energy and release it when needed.
Energy storage technology not only helps solve the intermittent problem of renewable energy,but also improves the stability and reliability of
the power system, while providing support for fields such as smart grids and electric vehicles.
According to data from the National Energy Administration,the cumulative installed capacity in China will reach 608.92
GW in 2023, a year-on-year increase of 55%. The installed capacity of industrial and commercial photovoltaics has also
experienced rapid growth,from less than 8GW of new installed capacity in 2021 to a surge of 236.7% in 2022,reaching 25.87GW;
In the first three quarters of 2023, the newly installed capacity has reached 34.16GW.
The newly added installed capacity in 2023 is about 22.6 million kilowatts/48.7 million kilowatt hours, an increase of over 260%
compared to the end of 2022, and nearly 10 times the installed capacity at the end of the 13th Five Year Plan period.
1、 Principles of Solar Power Generation
Solar power generation refers to the process of converting solar radiation into electrical energy.
Photovoltaic power generation is one of the main forms of solar power generation, which utilizes the photovoltaic effect to
directly convert solar radiation into electrical energy.
Specifically, photovoltaic modules are the core of photovoltaic power generation systems,consisting of multiple
monocrystalline and polycrystalline silicon photovoltaic cells connected in series.
When sunlight shines on high-purity silicon,electrons transition to form a potential difference, and light energy is
directly converted into direct current,and under the action of the inverter and boost system,it is converted into high-voltage AC power,
ultimately achieving the functions of electricity consumption and grid connection.
2、 Principles of Energy Storage Technology
Energy storage technology refers to the technology of storing energy in some form and releasing it when needed.
In solar power generation, energy storage technology is mainly used to solve energy storage problems,ensure a stable
power supply even when there is insufficient solar radiation.
Energy storage technology is mainly divided into three categories:
Physical energy storage,Chemical energy storage,and electromagnetic energy storage,
Among them,battery energy storage in chemical energy storage is the most commonly used energy storage method in solar power generation.
The battery energy storage system is configured with energy storage capacity according to the actual situation on site,and there are small
distribution cabinet type energy storage systems available.
There are two options for large-scale containerized energy storage
Distribution cabinet type energy storage is suitable for scenarios with small capacity configurations.
The PCS booster compartment and battery compartment are combined into one,with a small footprint
and convenient and flexible layout.
Containerized energy storage is suitable for situations with large capacity configurations,where the PCS booster
compartment and battery compartment are placed separately.
The area is relatively large and can be customized according to actual needs.
3、Core value of solar energy storage
1. Environmental protection and energy conservation:
Solar power generation does not emit harmful gases, does not pollute the environment,and has a repairing and mitigating effect on climate change.
Energy storage systems can store excess electricity and release it during peak usage periods,reducing reliance on traditional energy sources.
2. Economic benefits:
Although the installation cost is high, the long service life of solar power generation systems can significantly reduce long-term energy costs.
Meanwhile, energy storage systems can optimize energy utilization and reduce electricity bills.
3. Renewable energy:
Solar energy is a renewable energy source that will never be depleted and does not require reproduction costs.
4. Wide application range:
Solar power generation systems can be applied to various industrial and commercial occasions,Such as industrial parks,logistics centers,
commercial complexes, etc.
5. Improve power supply stability:
Energy storage devices can provide electricity in the event of insufficient solar radiation or grid failures, ensuring continuous power supply.
6. Optimizing energy structure:
By combining solar power generation and energy storage technology, the energy structure can be optimized and energy
utilization efficiency can be improved.
7. Policy support:
Relevant government departments at all levels have introduced corresponding policies to encourage users to actively develop distributed solar power
generation and energy storage systems,Promote the development of distributed energy storage construction.
